Used largely by companies in German-speaking countries where AG has a special meaning in company names, though use in Germany is restricted by court order.

In addition to its original intended use as a country code, and the secondary meaning as a type of company in German-speaking countries, the .ag domain has been marketed for use for agriculture-related sites, and for sites referencing the atomic symbol for silver, Ag. It also has a potential use for other domain hacks for English words that end in -ag.
